About this title The discipline of antenna theory has experienced vast technological changes. In response, Constantine Balanis has updated his classic text, Antenna Theory, offering the most recent look at all the necessary topics. New material includes smart antennas and fractal antennas, along with the latest applications in wireless communications. Like the previous editions, Antenna Theory, Third Edition meets the needs of electrical engineering and physics students at the senior undergraduate and beginning graduate levels, and those of practicing engineers as well.

Two operating modes are investigated; switched and phased modes. The arrays were fabricated on FR-4 substrates with 0. Measured and simulated results were compared. The printed V-shaped antenna array offers 2. Introduction Increased usage of tracking devices in cars raised the need for the development of highly accurate position determination systems.
One of the basic requirements for radio frequency RF vehicular localization is the accurate estimation of the direction of arrival DOA of the incoming RF signal . Recent advances in smart antenna technologies—antennas with digital signal processing DSP equipment—enabled the enhancement of antenna coverage and efficient utilization of the transmitted power. In a bid to accommodate the maximum possible number of users, cellular service providers are utilizing smart antenna systems to shape the radiation patterns to focus their transmit power in a given region.
The use of multiple receivers dictated the size of the overall system to be large making it difficult to deploy for several applications. For increased practicality, microstrip antenna arrays are used nowadays to save space and to decrease the overall profile of the system.
As the number of cars globally increases beyond the 1 billion mark , parking problems in densely populated cities have started to increase. Indoor, multistory parking lots are being considered as one of the most efficient ways of providing parking space for the available cars without interrupting the traffic flow. An emerging application of DF systems is for car localization in huge parking lots. The majority of modern cars are equipped with remote entry systems which can help in locating the car when the transmitter key is triggered within a specific distance from the receiver.
